Walpur Guiss

He has Skunk Kusai copy the blueprints of Astro Boy’s original plans. Walpur Guiss uses these to create his own robot named Atlas. However, he built Atlas with the inclusion of the Omega Factor, a device which gives robots the ability to lie, along with other negative traits. Likely because of this, Atlas eventually betrays Walpur Guiss.
